WHITE PAPER

Key Findings

Support for increased workloads, acceleration of application performance, and meeting critical elements of overall SAN performance

is key in the selection and deployment of an 8Gb HBA with the right architecture to scale and support robust databases, mail servers,

and secondary storage.

• Microsoft Exchange seats

– Driving Microsoft Exchange-like I/O loads in an attempt to saturate the HBAs showed 68 percent higher performance with the

8Gb HBA over the 4Gb HBA.

– The QLogic 2500 Series 8Gb FC HBA provided a 26 percent higher backup performance over the 4Gb HBA with 40 threads

per storage group using Microsoft Exchange 2007.

• D2D backup

– Using NetBackup 6.5, there was a 100 percent higher backup performance with the 8Gb HBA over the 4Gb HBA.

– Using NetBackup 6.5, it took half the time (50 percent) to backup 14GB of data using the 8Gb HBA versus the 4Gb HBA.

• Oracle Applications

– Using best-in-class Oracle and Intel

Stoakley Quad Core system, the 8Gb HBA was up to 90 percent faster than the 4Gb HBA

testing Online Transaction Processing (OLTP) with random and small 100 percent reads.

– When testing the Data Warehousing Application workloads, the 8Gb HBA was up to 102 percent faster than the 4Gb HBA.

White Paper Executive Summary It is imperative to deploy a scalable architecture to meet the evergrowing requirements of Storage Area Networks (SANs). The QLogic 2500 Series 8Gb Fibre Channel (FC) Host Bus Adapter (HBA) meets the need for high performance to support the volume of data or throughput (measured in MBps) and the load of data requests (measured by IOPS). Today’s SANs requires increased performance supporting common enterprise applications such as database, mail servers, and secondary storage.

White Paper Deploying 8Gb Fibre Channel today prepares the data center to take advantage of reduced backup windows and data-migration in D2D and data replication environments. The added throughput also alleviates pressure caused by sustained data growth rates and eliminates bottlenecks in the SAN. The following figure illustrates an increase of 100 percent in backup performance from 4Gb to 8Gb.

White Paper 8Gb Oracle Advantages backups.The following figure shows a 100 percent increase from 4Gb to 8Gb supporting high throughput, insert/update-intensive workloads that are typical for companies with large transaction processing applications. To test the scalability of the QLogic 2500 Series 8Gb FC HBA, the comparison between the 4Gb and 8Gb was tested using OLTP testing, Data Warehousing, and Oracle Web applications.

White Paper Oracle Web applications demand the highest levels of performance from their database servers and storage infrastructure. To satisfy this demand, organizations are making the transition to 8Gb Fibre Channel SANs, and IT decision makers are under pressure to select the right components to ensure a cost-effective and scalable solution. The QLogic 2500 Series 2500 8Gb FC HBA provides a critical element of overall SAN performance in the selection and deployment of the right architecture.

White Paper The superior scalability advantages demonstrated in these tests deliver practical benefits in real-life applications used by enterprise IT users: •• Lower hardware TCO, especially with emerging cost saving applications such as server virtualization and servers with multi-core processors. QLogic HBAs provide enough IOPS and throughput to account for the high bandwidth requirements for server virtualization, D2D, and remote mirroring applications.
